PAPI_remove_named_event \- 
.PP
removes a named hardware event from a PAPI event set.  

.SH SYNOPSIS

.PP
.SH "Detailed Description"
.PP 
A hardware event can be either a PAPI Preset or a native hardware event code. For a list of PAPI preset events, see PAPI_presets or run the papi_avail utility in the PAPI distribution. PAPI Presets can be passed to \fBPAPI_query_event\fP to see if they exist on the underlying architecture. For a list of native events available on the current platform, run papi_native_avail in the PAPI distribution.

   // Add Total Instructions Executed to our EventSet
   ret = PAPI_add_named_event(EventSet, EventName);
   if (ret != PAPI_OK) handle_error(ret);

   // Start counting
   ret = PAPI_start(EventSet);
   if (ret != PAPI_OK) handle_error(ret);

   // Stop counting, ignore values
   ret = PAPI_stop(EventSet, NULL);
